This invention relates to a disassembly device for a hydraulic coupling, comprising a support frame, a connecting rod, an electric hammer, and a pressing assembly. The connecting rod is rotatably mounted on the support frame for connecting the hydraulic coupling. The electric hammer is slidably mounted on the support frame, with its sliding direction aligned with the axial direction of the connecting rod. The drive end of the electric hammer is connected to the support frame via the pressing assembly. During disassembly, the electric hammer is pushed away from the hydraulic coupling, causing the high-frequency impact generated by the hammer along the pushing direction to be transmitted to the support frame via the pressing assembly. The support frame then transmits this impact to the hydraulic coupling via the connecting rod, thereby moving the hydraulic coupling and achieving disassembly. Its advantages include rapid disassembly of the hydraulic coupling while significantly reducing the risk of equipment damage.
